Abstract: Disclosed are surfactant-stabilized latex emulsions which can be used as binders in paper coating compositions. Such latex emulsions comprise an interpolymer formed by emulsion polymerizing monomers selected from vinyl esters, e.g., vineyl acetate; ethylene; certain unsaturated mono- and di-carboxylic acid materials such as acrylic acid or maleic anhydride; and certain polyethylenically unsaturated cross-linking co-monomers such as diallyl phthalate. These latex emulsions are stabilized with surfactants which are substantially free of environmentally suspect alkyl phenol ethoxylates (APEs). The paper coating compositions containing latex emulsion binders of this type exhibit especially desirable coating strength as quantified by the Dry Pick Values (as defined herein) which such compositions provide.

Abstract: Disclosed are improved carpet products made using certain types of coating compositions to secure carpet fibers to a carpet backing or substrates and/or to secure one or more carpet scrims or other layers to carpet backing. The coating compositions, which can be in the form of either precoating or skip coating compositions, are made from latex binder emulsions based on interpolymers emulsion polymerized from vinyl esters, ethylene, and a multifunctional cross-linking co-monomer such as an unsaturated silane. Such emulsions are also stabilized with surfactant emulsifiers but are substantially free of protective colloid stabilizers. The multifunctional co-monomer alters interpolymer molecular weight, branching and/or flow properties such that films formed from such interpolymers exhibit relatively low elongation values. When the emulsion binder exhibits such non-elongating film-forming characteristics, the carpet coating composition made from such binders can be easily processed without build-up on carpet processing apparatus. Such binder emulsions which are stabilized substantially only with surfactant emulsifiers, and not with protective colloids, also have excellent compatibility with other coating composition components.

Abstract: Disclosed herein are nonwoven fibrous structures for use as body fluid acquisition/distribution elements in personal care products. Such structures comprise natural and/or synthetic fibers wherein the fibers have been consolidated by application thereto, and by cross-linking of, a certain type of cross-linkable, vinyl acetate-ethylene (VAE) emulsion copolymer latex binder. The VAE latex binder is one which also comprises an added organic acidulant such as citric acid. Consolidation of the structures with VAE-based binders to which the organic acidulant has been added imparts to the resulting structures the ability to lower the pH of body fluids such as urine passing through the structures. This effect, in turn, provides odor control and skin care benefits to the absorbent articles, e.g., diapers and adult incontinence products, using such structures as acquisition/distribution elements.

Abstract: The present invention relates to a coating composition for fibrous substances containing 25 to 75 percent by weight of pigment, and 0.5 to 25 weight percent of a polymer comprising 1 to 15 percent by weight of one or more monomers having sterically hindered secondary amine groups and 10 to 40 weight percent of a carboxylic acid monomer. The coating is useful on fibrous and non-fibrous substrates on which liquid inks will be fixed. The non-ionic polymer becomes cationic when contacted by anionic inks, and the cationic nature of the coating provides the substrate with an excellent point of attachment for inks and dyes, resulting in bright, crisp printed images. The coating is especially useful for ink-jet printing on paper, paperboard, textiles, non-wovens, wood, and films.
